A bobbin winder is the part of a sewing machine that takes the thread from a spool of thread and winds it on the bobbin. The sewing machine bobbin is a mini-spool of thread, mâ¦ade of plastic or metal, that holds the thread that will be on the underneath portion of your fabric when you sew.
Pulling force and resistance. Solenoid pulling force is impacted by ampere turns. Ampere turns are a function of the current that passes through the coils and the number of turns of copper wire wrapped around the bobbin.The solenoid's size determines the amount of copper wire that can be used, so the main determinant of pulling force is the amount of current.Lower resistance leads to greater current flow. In other words, thick copper wire increases pulling force.he solenoid's size determines the amount of copper wire that can be used, so the main determinant of pulling force is the amount of current.
